I'd recommend counting up how many battles you had during the DT Hour.
So for example let's say you only did 18 battles. Your goal for the next DT should be 21 battles in the DT hour.
Also take a look at the amount of time between each of your matches. If you see that your averaging about 3-4 minutes between each battle, see what you can do to get your time down to 2-3 minutes per battle.
Since your playing a low star deck, just keep in mind to keep playing and hopefully winning with your low star cards against your ops' high star cards.
....most time wasters don't even use a calculator. once they know all is lost their only hope is that you get frustrated and leave the battle. thats why they wait until the red bar....they earn so much disrespect, they ruin our game and don't improve theirs. I wish there was a way to stop them
Time in tourny should def be reduced, I am not the best or even good, but i don't waste time during tournys! it drives me crazy when someone idles until they are dropped.. i have 100% rate! I don't leave the game so i gotta sit there and sit there! AHHHHHHHHH lol it does suck though.
I will play with some very very low star decks later and see how well i do. I usually just play with my normal deck but just in hopes of getting those extra credits for being in the top 1/3rd, but i'll try harder and maybe have some feedback!
